Basic Power Rule:
f(x) = cxⁿf’(x) = c·nxⁿ⁻¹Integration Rule 1: [tex]\int {cf(x)} \, dx = c\int {f(x)} \, dx[/tex]
Integration Rule 2: [tex]\int {f(x) \pm g(x)} \, dx = \int {f(x)} \, dx \pm \int {g(x)} \, dx[/tex]
Integration 1: [tex]\int {sec^2(u)} \, du = tan(u) + C[/tex]
Integration by Parts: [tex]\int {u} \, dv = uv - \int {v} \, du[/tex]
[IBP] LIPET: Logs, inverses, Polynomials, Exponentials, TrigStep-by-step explanation:
Step 1: Define
[tex]\int {sec^n(u)} \, du[/tex]
Step 2: Rewrite
[Integral - Alg] Separate Exponents: [tex]\int {sec^n(u)} \, du = \int {sec^{n-2}(u)sec^2(u)} \, du[/tex]Step 3: Identify Variables
Using LIPET, we define variables to use IBP.
Use Integration 1.
[tex]u = [sec(u)]^{n-2} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ dv = sec^2(u)du\\du = (n-2)[sec(u)]^{n-3} sec(u)tan(u) \ \ \ \ \ \ \ \ v = tan(u)[/tex]
Step 4: Integrate
Integrate [IBP]: [tex]\int {sec^n(u)} \, du = tan(u)[sec(u)]^{n-2} - \int [{tan(u)(n-2)[sec(u)]^{n-3}sec(u)tan(u)} ]\, du[/tex][Integral - Alg] Multiply: [tex]\int {sec^n(u)} \, du = tan(u)[sec(u)]^{n-2} - \int [{tan^2(u)(n-2)[sec(u)]^{n-2}}] \, du[/tex][integral - Int Rule 1] Simplify: [tex]\int {sec^n(u)} \, du = tan(u)[sec(u)]^{n-2} - (n-2)\int [{tan^2(u)[sec(u)]^{n-2}}] \, du[/tex][Integral - Pythagorean Identities] Rewrite: [tex]\int {sec^n(u)} \, du = tan(u)[sec(u)]^{n-2} - (n-2)\int [{[sec^2(u) - 1][sec(u)]^{n-2}}] \, du[/tex][Integral - Alg] Multiply/Distribute: [tex]\int {sec^n(u)} \, du = tan(u)[sec(u)]^{n-2} - (n-2)\int [{sec^n(u)-[sec(u)]^{n-2}}] \, du[/tex][Integral - Int Rule 2] Rewrite: [tex]\int {sec^n(u)} \, du = tan(u)[sec(u)]^{n-2} - (n-2) [\int {sec^n(u)} \, du - \int {[sec(u)]^{n-2}} \, du ][/tex][Integral - Alg] Distribute: [tex]\int {sec^n(u)} \, du = tan(u)[sec(u)]^{n-2} - (n-2) \int {sec^n(u)} \, du + (n-2)\int {[sec(u)]^{n-2}} \, du[/tex]Rewrite: [tex]\int {sec^n(u)} \, du = sec^{n-2}(u)tan(u) - (n-2) \int {sec^n(u)} \, du + (n-2)\int {[sec(u)]^{n-2}} \, du[/tex][Integral - Alg] Isolate Integral Term: [tex]\int {sec^n(u)} \, du + (n-2) \int {sec^n(u)} \, du = sec^{n-2}(u)tan(u) + (n-2)\int {[sec(u)]^{n-2}} \, du[/tex][Integral - Alg] Combine Like Terms: [tex](n - 1)\int {sec^n(u)} \, du = sec^{n-2}(u)tan(u) + (n-2)\int {[sec(u)]^{n-2}} \, du[/tex][Integral 2 - Alg] Rewrite: [tex](n - 1)\int {sec^n(u)} \, du = sec^{n-2}(u)tan(u) + (n-2)\int {sec^{n-2}(u)} \, du[/tex][Integral - Alg] Isolate Original Integral: [tex]\int {sec^n(u)} \, du = \frac{sec^{n-2}(u)tan(u)}{n-1} + \frac{n-2}{n-1} \int {sec^{n-2}(u)} \, du[/tex]And we have proved the Reduction Formula!

You download 4 songs for $5. Write an equation that uses the constant of of
proportionality to describe the relationship between the cost in d dollars
for s songs.
Answer:
The equation is;
d = 1.25s
Step-by-step explanation:
Here, we start by getting the price of a single song
From the question;
4 songs = $5
Thus, 1 song will be $5/4 = $1.25
So the proportionality constant is $1.25 per song
To write the relationship, we have;
d = 1.25s
Where d is the cost in dollars and s is the number of songs

4. Write an explicit formula for the sequence 6,2, -2, -6, -10.... Then find the 12th term
Answer:
-38
Step-by-step explanation:
general formula
a + (n-1)(d)
formula for this question
6 + (n-1)(-4)
find d
2-6=-2-2
-4=-4
d=-4
a=6 d=-4
12th term
T12= 6+(12-1)(-4)
= 6 + (-44)
=-38
hope this helps :)

If one cup is equal to 8 fluid Ounces, how many fluid ounces are in 3 cups?
Answer:
24 fluid oz
Step-by-step explanation:
1 cup = 8

3 cups = triple, or 24
Solve:
4(x-8) > 3 - (2x + 7)
A. 4 2/3
B. 6 2/3
C. 6
D. 7
Answer:
A. 4 2/3
Step-by-step explanation:
4(x-8) > 3 - (2x + 7)
4x-32 > 3 -2x -7
4x - 32 > -4 -2x
6x -32 > -4
6x > 28
divide both sides by 6
6 divide by 6 is 1
28 divide by 6 is simplified to 14/3 which can be changed into a mixed number 4 2/3

Answer:
#2 & #4
Step-by-step explanation:
So first lets plug this into point slope form which is
y-y₁=m(x-x₁)
So given the points (1,-7) and the slope -1, we can plug it into this equation
y+7=-1(x-1)
y+7=1x+1
y=1x-6
So you're answers to click would be, #2 & #4
